Title: Improvements in or relating to nuclear particle discriminators
Inventor: BROOKS FRANCIS DEY
IPC: G01T1/208
Filed: 1958-09-12
Abstract: 862,331. Nuclear particle discriminators. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Aug. 26, 1959 [Sept. 12, 1958], No. 29358/58. Addition to 823,263. Class 40(3). In a nuclear particle discriminator circuit as described in the parent Specification use is made of the opposite polarity of pulses from the last dynode and the anode of the photomultiplier to facilitate subtraction. Integrated negative pulses h, Fig. I representing scintillations pulse area developed across resistor R7, Fig. 1, and non-integrated positive pulses hc representing scintillation pulse amplitude developed across resistor R9 pass through attenuators R13, R15, C6 and R12, R14, C5 respectively giving a difference pulse hD equal to their algebraic sum (absolute difference) across resistor R16. The difference pulse is applied to a discriminator whose acceptance level is set to level D, Fig. 2, by applying the h and hD pulses to the X and Y plates respectively of an oscilloscope. It then accepts neutron pulses while rejecting gamma ray pulses. By changing the relative magnitudes of resistors R7 and R9 the h pulses may be obtained from the dynode and pulses hc from the anode. Resistors R7 and R9 may be replaced by potentiometers, Fig. 3 (not shown) to permit equation of the pulses applied to the diodes.

Abstract: 510,433. Coating surfaces by applying powdered materials. PEARCE, J. H. G., and PEARCE SIGNS, Ltd. Oct. 27,1937, No. 29412. Drawings to Specification. [Class 95] [Also in Group XV] In the manufacture of a fluorescent electric discharge device having an internal coating of fluorescent material, a uniform layer of a liquid binder for the fluorescent material is applied to the inner surface of the tube or envelope of the device by introducing the binder into the tube or envelope and then passing a stream of liquid, which does not adhere to the walls of the tube or envelope and which is immiscible with the binder, through the tube or envelope. Mercury is a suitable liquid for this purpose, and it may be passed through the tube by pressure or by suction, removing excess binder and leaving a thin uniformly distributed layer thereof, free from streaks or blemishes. The tube may be warmed during and/or immediately before the flow of mercury therethrough. The fluorescent material, in powder or other form, may be subsequently introduced into the coated tube, or may be previously incorporated with the binder.

Abstract: 1,112,653. Seismic wave generators. GENERAL DYNAMICS CORPORATION. 12 July, 1965 [13 July, 1964], No. 29446/65. Heading H4D. [Also in Division F2] Seismic waves are generated by applying time-varying forces to each of two members in the direction of the other, one member being anchored to the earth below its surface and the other member being on the earth's surface, and it is arranged that the earth between the members is always in compression. In the embodiment the anchor includes a set of elongated shoes 21 interconnected for movement toward and away from the axis of the hole in the earth, and a bladder 39 encircled by the shoes and when inflated causing the shoes to move into contact with the side wall of the hole so as to immovably engage it, Figs. 4, 5, and 6. The bladder is inflated with dry nitrogen or air via a quick-release device 43, Fig. 4; to keep the bladder from contact with the side wall of the hole, a member 45, Fig. 6, is welded to a side edge of each shoe. Tension bars 29, Figs. 1, 4 and 5, of T-shaped stock connect the anchor to a power system 17, each bar being connected to a shoe by a plate 51, Fig. 4. The power system is mounted on a platform 59, Fig. 2, which has as its base a force plate 19, Fig. 3, urged downwardly by an hydraulic system, Fig. 8 (not shown), to generate a seismic wave. The hydraulic system includes a low-pressure accumulator 85 assisting in cooling of the hydraulic fluid, in absorbing hydraulic shock, and in catering for thermal expansion and contraction of the hydraulic fluid; a signal of selected frequency in the range 18 to 90 c/s. actuates a servo valve 81 to cause seismic wave generation.

Title: Process for the manufacture of polyvinyl alcohol of high purity
IPC: C08F8/12
Filed: 1955-10-21
Abstract: <PICT:0818294/IV (a)/1> <PICT:0818294/IV (a)/2> Polyvinyl alcohol of high purity is made by hydrolysing a carboxylic acid ester of polyvinyl alcohol at a raised temperature in the presence of water and an acid catalyst, the carboxylic acid being progressively removed by extraction. Polyvinyl formate and acetate are the specified starting materials.  The liberated acid may be extracted at a raised temperature after the greater part (e.g. at least 90 per cent) of the polyvinyl ester has been hydrolysed and until more than 99 per cent of the polyvinylester has been hydrolysed and at least 95 per cent of the carboxylic acid has been extracted.  The extraction may take place by the addition of a liquid in which the acid dissolves but the alcohol does not, e.g. isopropyl ether, 2 - butanone, 2 - pentanone, methyl isobutyl ketone, isophorone, tributyl phosphate or mixtures thereof and the residual extraction liquid removed by distillation or extraction with a volatile solvent, e.g. butyl alcohol.  Referring to the drawing, the mixture for extraction may be fed into tube 1 containing plates 3 vertically vibrated by member 2 through conduit 4 at 60 DEG  C. and extraction medium through conduit 5 at 60 DEG  C. The extract is led off through conduit 6 and the polyvinyl alcohol concentrate through outlet 7.  The extraction is repeated.
